How to generate symbol map in gwt using maven?

问题:

I want to generate symbol map file in gwt using maven commandline option? I tried with -extra WEB-INF/classses but its not working.

Basically you want to specify maven plugin configuration values/options.

Here you have the general approach: LINKE

Besides that you have to know the plugin prefix that you can find on the GWT plugin page (there are several GWT maven plugins)

EDIT: added a gwt plugin example: Just define the ${} snippets in your gwt property section and you will be fine.
